Why DTAC, and Why Most Indians Pick It
DTAC (now branded dtac TriNet after their network merger) sits in the middle of the Thai big-three: AIS is the dominant market leader with the widest coverage, TrueMove H is the cheap disruptor with a thinner rural network, and DTAC splits the difference. For Indian travellers, DTAC usually wins on three things: pricing that competes with TrueMove without the rural dead zones, a tourist SIM that’s priced in baht (no hidden “free apps” catch), and physical retail at every Thai airport arrivals hall so you walk out of immigration already on 4G.
The catch nobody warns you about: DTAC’s English-language website is half-baked, and most in-store staff in tourist zones speak basic English. Bring a screenshot of the plan you want on your phone, point at the price, hand over your passport, done.
DTAC Tourist SIM Plans (Current Prices)
DTAC currently runs two prepaid tourist SIMs aimed at short-stay travellers, plus a third option called “dtac Go” if you’re staying longer or want to top up flexibly.
| Plan | Validity | Data | Price | Best for |
|---|---|---|---|---|
| dtac TriNet Tourist 8-day | 8 days | 15 GB 4G/5G | ₹859 (~299 THB or ~$8.91) | 1-week Bangkok + Chiang Mai |
| dtac TriNet Tourist 15-day | 15 days | 30 GB 4G/5G | ₹1,433 (~499 THB or ~$14.86) | 2-week Thailand loop |
| dtac Go (PAYG) | 30 days from first use | None included, pay per GB | ₹141 (~49 THB or ~$1.46) SIM + top-up | Long stays, variable use |
All three plans include free local calls (within the dtac network only, with small per-minute fees for other networks) and free incoming calls worldwide. The 8-day and 15-day tourist SIMs come with the data pre-loaded, so you don’t need to mess with USSD codes or the dtac app right after a 12-hour flight.
Subodh’s Pro Tip: Buy the 15-day 30 GB plan even if you’re staying only 10 days. The unused data doesn’t roll over, but the per-GB cost is half of the 8-day plan, and you never have to ration Maps and Grab usage on long bus rides.
DTAC vs AIS vs TrueMove H: Honest Comparison
This is where the other guides under-deliver. They list DTAC plans, then wave vaguely at “other carriers exist.” Here’s the actual comparison that matters at Suvarnabhumi arrivals.
| Factor | dtac TriNet | AIS | TrueMove H |
|---|---|---|---|
| 15-day tourist SIM | ₹1,433 (~499 THB or ~$14.86) / 30 GB | ₹1,720 (~599 THB or ~$17.84) / 30 GB (₹1,146 (~399 THB or ~$11.88) / 15 GB) | ₹1,433 (~499 THB or ~$14.86) / 30 GB |
| 4G/5G coverage in Bangkok | Excellent | Excellent | Excellent |
| Phuket / Krabi / islands | Excellent | Excellent | Good (some Ao Lo spots drop to 3G) |
| Northern hills (Pai, Mae Hong Son) | Good | Excellent | Weak |
| Deep rural (northeast Isaan) | Good | Excellent | Fair |
| App / English UX | Average | Best-in-class | Weak |
| Airport counter presence | All major airports | All major airports | Most airports, smaller kiosks |
AIS is the objectively bigger network, but their 30 GB plan costs ₹1,720 (~599 THB or ~$17.84) vs DTAC’s ₹1,433 (~499 THB or ~$14.86). The ₹1,146 (~399 THB or ~$11.88) AIS 15-day plan is cheaper than DTAC’s 8-day but only gives you 15 GB. TrueMove H matches DTAC’s price but loses coverage in the hills and smaller islands where DTAC holds up.
For first-time India-to-Thailand trips covering Bangkok, Chiang Mai, and a beach island, DTAC is the safe pick. If you’re sticking only to Bangkok and Phuket, save money with TrueMove H. If you’re going to be driving through Mae Hong Son and Pai, pay the extra ₹287 (~100 THB or ~$2.98) for AIS. Our 7-Eleven SIM guide covers walk-in rates across all three carriers if you want a full price breakdown.
Where to Buy DTAC SIM Cards in Bangkok
At the airport (recommended)
Suvarnabhumi Airport (BKK): DTAC has a branded counter in both arrivals concourses, open roughly 24/7 to match international flight waves. The walk from immigration to the DTAC counter is 2-3 minutes and signposted in English. The counter staff will scan your passport, snap a photo for Thai government SIM registration, hand you a sealed SIM pack, and activate it on the counter.
Don Mueang Airport (DMK): Smaller DTAC kiosk in the domestic/international arrivals area. Same process, slightly longer queue at odd hours because there’s only one counter serving all carriers. Our Don Mueang Airport guide covers terminal layout and ground transport if you’re transiting.
Phuket Airport (HKT): DTAC kiosk in arrivals, open 6 AM to midnight. Same pricing as Bangkok, no airport markup for the tourist SIM.
Safety Alert: Skip the “free SIM / airport WiFi” touts who approach you before passport control. They’re selling tourist SIMs at inflated ₹2,297-₹2,872 (~800-1,000 THB or ~$23.83-$29.79) that you’d otherwise get at the counter for ₹859 (~299 THB or ~$8.91). Walk past, find the official counter.
In the city
Any 7-Eleven in Thailand can sell and top-up a dtac Go SIM. The downside: the staff activation flow for first-time tourist SIMs is awkward at 7-Eleven, because the SIM-porting takes 30-60 minutes and needs a passport scan that their terminal doesn’t always do cleanly. Buy tourist plans at the airport; use 7-Eleven only for top-ups once you’re set up.
Central Bangkok has multiple dtac service centres (the big branded shops, usually marked “dtac Center”). MBK, CentralWorld, and Siam Square all have one. These are the best place to sort out plan changes, mobile banking SMS issues, or 5G APN settings if the auto-config doesn’t fire.
Activation: What Happens
The activation flow at any official counter is the same and takes about 5 minutes:
- Hand over your passport. Counter staff scan it into the Thai government’s mandatory SIM-registration system.
- Pick the plan (point at your screenshot).
- They slot the SIM into a spare demo phone, confirm signal and data, hand it to you to swap into yours.
- You get a Thai mobile number printed on the receipt. Save it, you’ll need it for Grab, food delivery apps, and OTPs.
Important details that don’t make it into the brochure:
- Passport validity should be more than 6 months from your entry date. Some counter staff may flag passports with less validity, though rules vary by location, so carry a backup ID just in case.
- Photo/scan of your visa isn’t needed. The TDAC digital arrival card QR counts as your entry record.
- eKYC can fail for Indian passports occasionally because of MRZ (machine-readable zone) scan quality. If the staff member frowns and tries twice, ask them to clean the passport page with a cloth and try a third time. Failing that, they can fall back to manual entry on a tablet, which adds 10 minutes.
- Porting from another Thai SIM (if you’ve been here before on AIS or TrueMove) takes 24 hours. Plan your tourist SIM purchase for the first hour, not your last day.
Data Speeds and APN Settings
DTAC TriNet posts 5G in Bangkok, Chiang Mai, Phuket, Pattaya, Hua Hin, and Krabi town. 4G everywhere else with a tourist SIM. Typical 5G speeds in Bangkok central run well above 100 Mbps, dropping to 30-60 Mbps on 4G in rural areas.
APN auto-configures on iOS and modern Android (Pixel, Samsung, OnePlus). If you’re on a Xiaomi or Realme and data doesn’t connect within 5 minutes, manually set:
- APN:
internet - Username: leave blank
- Password: leave blank
If still stuck, dial *3000 from the dtac app or call 1678 (English line, 24/7).
DTAC for Indian Apps and Banking
Network-wise DTAC works fine with WhatsApp, Telegram, Google Maps, Grab, IRCTC, and all standard Indian apps. The two things Indian travellers occasionally trip on:
- OTP SMS delivery to Indian numbers: works, but occasionally delayed 30-90 seconds versus home. If you’re trying to log into HDFC netbanking or Paytm abroad, give it 2 minutes.
- Indian bank fraud alerts: some Indian banks freeze cards based on “impossible travel” (you charged in Delhi 12 hours ago, now Bangkok). Pre-warn HDFC, ICICI, SBI before leaving India. The dtac SIM doesn’t help with this; it’s a separate fraud system.
eSIM Alternative: Skip the Physical SIM Entirely
If your phone supports eSIM (iPhone XR and newer, Pixel 4 and newer, most Samsung Galaxy S20+), you can skip the airport queue and arrive already online. The dtac eSIM works on the same TriNet network.
For 8-15 day Thailand trips, the cleanest eSIM option for Indian travellers is Check Nomad eSIM plans, which ships a regional Asia profile you can install before you board your flight. Pricing is comparable to DTAC’s tourist SIM after you include the airport time cost.
Pick eSIM if: your phone supports it, you don’t want to queue on landing, and you don’t need a Thai phone number for calls or local OTPs.
Pick physical dtac SIM if: you want a Thai mobile number for OTPs and calls, your phone is older, or you’re using a dual-SIM phone where you want your Indian SIM as the second slot.
Pitfalls and Things to Know
No voice roaming included. The dtac tourist SIM covers you in Thailand only. If you cross the border into Laos or Cambodia, your data dies at the border. Top up roaming add-ons inside Thailand via the dtac app before crossing, or buy a local SIM at the land border.
SIM lock to first device. The first phone you slot the SIM into registers it. Popping it into a new device later requires re-registering at a dtac Centre with your passport, takes 15 minutes.
No refunds on unused days. Buy the 15-day plan only if you’ll genuinely use it. If your trip is 7 days exactly, the 8-day plan is ₹287 (~100 THB or ~$2.98) cheaper per unused day you “waste.”
Top-up via 7-Eleven or app. The My dtac app accepts Thai credit cards, PromptPay, and TrueMoney wallet. International Visa/Mastercard top-up works but with a 3% FX fee. Cheapest path: walk into any 7-Eleven, hand them cash, ask for “dtac top-up 100 baht,” they swipe.

FAQ
Will my Indian phone work with dtac? Yes, almost certainly. All Indian phones sold since 2018 are multi-band 4G/5G and support Thai carrier frequencies. If your phone is locked to a specific Indian carrier (older Jio phones sometimes are), ask to get it unlocked at home before leaving.
Can I use dtac in other Southeast Asian countries? No, the tourist SIM is Thailand only. For a multi-country trip, either buy separate SIMs at each border or use Nomad’s regional eSIM profile, which covers Thailand, Vietnam, Laos, and Cambodia on one activation.
Is there a true unlimited plan? No. DTAC’s tourist SIM caps at 30 GB on the 15-day plan. After the cap, speed drops to 384 kbps, usable for WhatsApp and Maps but not video.
Do I need to show proof of onward travel? Not for SIM registration, only for the TDAC arrival card. Thai SIM sellers don’t ask about flight tickets.
Can I get a Thai number before landing? Only via eSIM (Nomad, Airalo, Holafly sell before arrival). Physical dtac SIMs require in-store passport registration.
Is dtac 5G worth the upgrade? In Bangkok and Chiang Mai central, yes, 4G is fine for most tourists. 5G matters for hotspotting to a laptop.
Subodh’s Take
For one week in Bangkok and Chiang Mai, the ₹859 (~299 THB or ~$8.91) dtac 8-day plan is the right call. For anything longer than 10 days, jump straight to the 15-day 30 GB at ₹1,433 (~499 THB or ~$14.86) and stop thinking about it. DTAC isn’t always the absolute cheapest, but it’s the closest to “set and forget,” which is what you want after a 4 AM Suvarnabhumi landing.
